FLOW RATE DATA STORAGE DEVICE

Japanese Patent JP3267729

B2

PURPOSE: To obtain the precise relationship between pieces of data by a method wherein pieces of measured data by a flow-rate sensor and by a sensor other than it are stored and processed on the basis of the reference time.
CONSTITUTION: A flow-rate sensor 7 outputs flow rate data to a CPU 2 inside a flow rate data storage apparatus 1 each time a gas flows in a gas pipe 10 at a definite flow rate. An indoor temperature sensor 8 and an outdoor temperature sensor 9 always measure a temperature, and they output data to the CPU 2. A setting device 6 is connected to the apparatus 1, and it is used when the apparatus 1 is instructed by an operator about the range of flow rate data and temperature data which are to be stored in a RAM 3 in the apparatus 1, when flow rate data and temperature data which have been stored in the RAM 3 are read out by the operator and when the time is set on the apparatus 1 by the operator. A clock circuit 5 which is connected to the CPU 2 outputs the operating clock of the CPU 2, and the CPU 2 can obtain the present time on the basis of the time which has been set in the setting devide 6.
